CONCRETE-HANDLING APPARATUS.

Application filed November 20, 1922. Serial No. 602,048.

To all whom "it may concern.

Be it known that we, WILLIAM H. Instant and ALVIN C. RAsMUssnN, citizens of the United States residing at Indianapolis, in

the county of Marion and State of Indiana,

which raises the material to the desired.

height and then delivers the same to the chutes so that under the influence of gravity the material will be conveyed to the point of deposit. 1

One of the objects of our invention is to so construct an apparatus of the above character that the load on the'mast will be so distributed and balanced as to reduce twisting and tilting strains on the mast to a minimum. Another object of our invention is to provide means whereby the vertical position of the bucket-discharging mechanlsm and the delivery chutes may be readily shifted to accommodate changing heights of structure. Another object of our invention is to provide means whereby the chute mechanism and the material delivery mechanism may be reversed as to position thus permitting of the delivery ofthe material over a wide range without any necessity of turning the mast which, in an apparatus of this character, is usually substantially secured at itsbase. I

For the purpose of disclosing the invention, one embodiment thereof is illustrated in the accompanying drawings, in which Fig. 1 is a front'elevation of an apparatus embodying the invention;

Fig. 2 is a side elevation thereof; I Fig. 3 is an enlarged detail of the side elevation showing more fully the construction of the. delivery apparatus. and the mounting for the chutes;

Fig. 4 is an enlarged detail oi the front elevation. having particular reference to the delivery apparatus, and

. Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1.

In the construction illustrated, the mast or tower 1 as shown comprises four corner posts which. are formed of angle iron, and diagonal braces which connect the angle iron posts together. The mast may be made in sections for convenience of transportation, the sections being joined together in erection by suitable joint plates 2. This mast is supported at its top by guy linesB, andby guy. lines 4: at suitable intermediate points depending upon the total height of the mast.

Near the upper end of the mast is provided a head-frame for supporting the chute hopper 5. This frame comprises a pair of horizontally disposed arms 6 extending forwardly from the mast and suitably braced by arms 7, the inner ends of which are securedto'the mast and the outer ends of which are secured to the forwardly extending arInS 6. T ransversely of the arms 6 and therefore transversely of the mast are a pair of arms 8 which project beyond one side of the mast. At the outer ends of these arms 8 are a pairof vertically extending arms 9 secured to the arms 8 and suitably braced by plates 10 at their corners and bya brace 11 and bracing arm 12 along the side. The hopper 5 is secured to and supported by the lower ends of thesearms to one side of the mast. Pivoted to the upper part of the hopper 5 are two pairs of links 13 and 14 the lower ends of which are pivoted to the bridge pan 15 of the hopper so that the bridge pan may be swung into or out of the hopper and at the same time maintain substantial parallel relation with respect to the bottom of the hopper.

The hoisting bucket for the material com:

prises a hopper bottom bucket '16 having a side delivery mouth 17 controlled bya pivoted gate 18 and adapted to deliver the concrete or other material to the chute hopper I 5, the bridge pan 15 providing a bridge between the'delivery end-of the bucket and the hopper. The bucket is mounted on a traveling carriage 19 'whichtravels vertically on themast. This carriage at its lower end is provided with a pair of rollers or wheels 20 bearing on the front face of the two front angle posts or the mast and at its upper end with a pair of wheels or rollers 21 engaging behind the angles of the front posts of the mast so that the frame and bucket willbe guided in their vertical movement. The

bucket is elevated by a cable 22 operating over suitable sheaves 23 in the top of the mast and passing beneath a sheave 24 at the bottom of the mast to suitable hoisting apparatus 25. For tripping the gate 18 and opening the same when the bucket reaches the limit of its upward travel alever 26 is pivotedto'the side of the bucket and connected by a cable 27 to thegate 18. At its rear end it is-adapted to engage a suitable stop'267 on the head-frame so that as the bucket reaches the limit of its movement the lever will be operated to open the gate; At

thesame time the top of the" bucket will engage a pivoted lever 28 connected .by operatin'g rods 29 with the bri'dge pan15 and move the bridge pan beneath the delivery" mouth l'iof the bucket. It will benote'd that the delivery mouth '17" extends transversely of 'the-bucketand the bucket therebyihas aside chutes may distribution.

delivery instead of the ordinary front delivery, and thatthe .hopper'chute '5 and bridge pan l5 extendtransversely to the mast so that the material from the bucket is delivered to one side ofthe mast instead of the frontof the mast as has heretofore been the custom. i

Onthe rear of the mast there is provided a bracket'SO on whichis pivotally supported a 'deliverychu'te 31. "This chute on itsunder side is provided with a'pivotpin 32 suitably pivoted in a 'socket'33 on thebracket 30 so that thefchute'may be swung on this pivot to various positions. The outer end of the chute is supported by aboom' line 3 iwhich extends from the outer en'd of the chuteto a bracket 35"secured at a'point on" the mast above bracket 30 and coinciding pivotally with pin 32. By this arrangement the pivot and supporting p'ointofthe inner end of the chute and the upper end of the boomline are "brought well towards the mast so thattwistingstrains on themast when the outer end' of the chute is swung to one side or the other" are substantially reduced; A

second chutei4c' carried from'and beneath the discharge end of chute39jiscustomarily ments of the two chutes, anypoint within the circular area which they may describe can be conveniently reached. Additional b'e use'dto extend the area of It WllllbdllOilQCl thatthe bucket and chute hopper are mounted on the front of the mast-and have a side ortransverse delivery,

and that theconveyor chuteis' mounted on wwiil-alsozbe seen @that :the del-ivery ei1d of the chute hopper 5 is slightly beyond the side of the mast. For conveying the material from the chute hopper 5 to the delivery chute 31 we provide a conveyor chute 39, the spout 40 of which is directly over the hopper of the chute 31 and the hopper 41 of which is beneath the hopper chute 5. The receiving end of the conveyor chute is supported from the hopper 5 by means of a bolt 42 secured in an angle 43 mounted on the hopper chute. The delivery end of the chute 39 is supported from the head 36 of chute 31. By reason of the fact that the elevating bucket 16 and hopper chute 5 have a side delivery the conveyor chute 39 may be made straight'and short thereby avoiding turns or twists in the chute which would tend to obstruct the ready flow of the, material.

The front and rear posts of the mast are provided with bolt holes 45 which are regularly spaced throughout the height of'the mast an equal distance apart. These holes are provided for securing to the front face of the mast the head-frame or bucket-discharging mechanism and its associated parts, and to the rear face of the mast the'chute supporting brackets.

The spacing of the bolt holes in the parts constituting the head-frame and the chute supporting brackets is the same as the spac ing of'the holes in-the mast. This arrangemerit provides means whereby the headframe on one side and the chute-supporting brackets on the other may be secured to the mast at any vertical height desired and also whereby the parts may be reversed from one side of the mast to the other. Due to the fact that the traveling frame support for the bucket may be readily disconnected from the mast and the rear mast posts are the same as the front mast posts the bucket likewise may be transposed from either side of the mast to the other. By this arrangement delivery may be made to any point within the periphery of a circle having the mast as its center and described by the combined length of the chutes as a radius and at any height-within the vertical range of the mast. While the terms front "and rear have beenappliedto certain sides of the mast,

We claim as our invention: a
